Kwisiseko setransformer nganye kukho into ebalulekileyo - isiseko setransformer. Isiseko sinoxanduva lokuvumela i-magnetic flux efunekayo ekusebenzeni kwetransformer. Eli nqaku liphonononga iintlobo ezahlukeneyo zee-transformer cores, iimpawu zazo, kunye nokusetyenziswa kwazo kumashishini ahlukeneyo.

Ukubaluleka kweeTransformer Cores

Ii-transformer cores zisebenza njengomqolo wenkqubo yonke ye-transformer. Zibaluleke kakhulu ekuqinisekiseni ukuguqulwa kwe-voltage okusebenzayo kunye nokunciphisa ukulahleka kwamandla. Umsebenzi oyintloko we-core kukubonelela ngendlela yokuba i-magnetic field idlule kuyo, okwenza kube lula ukuguqulwa kwamandla ombane ngokufanelekileyo. Uyilo kunye nokukhethwa kwezinto ze-transformer core kunefuthe elikhulu ekusebenzeni kwayo iyonke, kubandakanya ukusebenza kwayo kakuhle, ukuthembeka, kunye nokukwazi kwayo ukuphatha amandla.

Ukuqonda Ukwakhiwa Kwe-Transformer Core

Ukwakhiwa kwe-transformer core kubandakanya ukugquma amaphepha ezinto ezitsala amandla ukuze kuncitshiswe ilahleko yamandla ebangelwa yimisinga ye-eddy. Ezi laminations ziqiniswe ngokuqinileyo kwaye zidityaniswe kunye kusetyenziswa ii-insulation coating ukunciphisa ilahleko yamandla ngenxa ye-hysteresis. Imilo kunye nobukhulu be-core ziyahluka ngokuxhomekeke kuyilo lwe-transformer kunye nesicelo sayo. Ezona ntlobo ziqhelekileyo ze-core ziquka i-E shape, i-C shape, kunye ne-O shape.

Iintlobo ezahlukeneyo zeeTransformer Cores

Uhlobo lwezinto ezisetyenziswa kwi-transformer core luchaphazela kakhulu ukusebenza kwayo kunye nokusebenza kwayo kakuhle. Nazi iintlobo eziphambili zee-transformer cores ezisetyenziswa kwizicelo ezahlukeneyo:

1. Umongo wentsimbi

I-iron core yenye yezona ntlobo zisetyenziswa kakhulu zee-transformer cores. Iqulethwe ngamacwecwe e-iron okanye entsimbi aqinisiweyo, anika iipropati ezintle zemagnethi. Ukungena kwe-iron ngemagnethi ephezulu kunciphisa ukulahleka kwamandla kwaye kuvumela ukudluliselwa kwamandla ngokufanelekileyo. Ii-iron cores zisetyenziswa rhoqo kwii-power transformers, ii-high-voltage transformers, kunye nee-distribution transformers ngenxa yokusebenza kakuhle nokuthembeka kwazo.

Iintsimbi zentsimbi zibonelela ngeendleko eziphantsi xa kuthelekiswa nezinye izinto, nto leyo eyenza ukuba zibe lolona khetho lukhethwayo kwiitransformer ezisebenza kumaza aphantsi. Nangona kunjalo, zichaphazeleka lula kumanqanaba aphezulu okusasazeka, nto leyo ethintela ukusetyenziswa kwazo kwiindawo ezifuna amandla aphezulu emagnethi.

2. Undoqo weSilikhoni yeNsimbi

Ii-silicon steel cores, ezaziwa ngokuba yi-electrical steel okanye i-lamination steel, zisetyenziswa kakhulu kwi-power transformers, ii-autotransformers, kunye nee-reactors. Zenziwe nge-silicon alloy enciphisa ukulahleka kwamandla okubangelwa yi-magnetic hysteresis. Ukongezwa kwe-silicon kwintsimbi kwandisa ukuxhathisa kwayo, kunciphisa ukulahleka kwe-eddy current.

Ii-cores zesinyithi zesilicon zibonisa iimpawu ezintle zemagnethi, nto leyo eyenza ukuba zisebenze kakuhle kakhulu kwii-transformers ezisebenza kumaza aphantsi naphakathi. Zikwabiza kancinci kwaye zinozinzo oluhle lobushushu. Ukumelana okuphezulu kwesinyithi sesilicon kuvumela ukusetyenziswa kwee-laminations ezincinci, kunciphisa ilahleko ze-core kunye nokuphucula ukusebenza kakuhle kwe-transformer iyonke.

3. Undoqo we-Amorphous Alloy

Ii-amorphous alloy cores ziya zithandwa kakhulu kuyilo lwe-transformer yanamhlanje ngenxa yeempawu zazo ezikhethekileyo zemagnethi. Ezi cores zenziwe ngeeribhoni ezibhityileyo ze-amorphous alloy, ezihlala zenziwe ngentsimbi, i-boron, kunye ne-silicon. Ukungabikho kwesakhiwo sekristale kwii-amorphous alloys kunciphisa kakhulu ukulahleka kwamandla ngenxa ye-hysteresis kunye nemisinga ye-eddy.

Ii-Amorphous alloy cores zinomoya ophezulu wokungena kunye namandla aphantsi okunyanzela, nto leyo eyenza ukuba zilungele ii-high-frequency transformers kunye nee-small-size transformers. Ukulahleka kwazo okuphantsi kuncedisa ekwandiseni ukusebenza kakuhle kwamandla kunye nokuzinza kokusingqongileyo. Nangona kunjalo, ii-amorphous alloy cores zibiza kakhulu, nto leyo ethintela ukusetyenziswa kwazo kwezinye iinkqubo.

4. I-Ferrite Core

Ii-ferrite cores zisetyenziswa kakhulu kwii-transformers ezisebenzisa i-high-frequency kunye ne-low-power, ezifana nezo zifumaneka kwizixhobo zonxibelelwano kunye nezixhobo zamandla ze-switch-mode. Ezi cores zenziwe nge-ceramic compound ye-iron oxide kunye nezinye izinto, kubandakanya i-nickel, i-zinc, kunye ne-manganese.

Ii-ferrite cores zineempawu ezintle zemagnethi kumaza aphezulu kwaye zibonisa ilahleko ephantsi yomsinga we-eddy. Zinokumelana okuphezulu, nto leyo ezenza zifaneleke kwizicelo ezifuna ukumelana okuphezulu kombane. Ukongeza, ii-ferrite cores zibonelela ngozinzo oluhle lobushushu kwaye azibizi kakhulu xa kuthelekiswa nezinye izixhobo.

5. Umthombo woMoya

Ngokungafaniyo nezinye iintlobo zee-cores, ii-air cores azinazo naziphi na izinto ze-magnetic. Endaweni yoko, zixhomekeke emoyeni njengesixhobo sokuhambisa i-magnetic field. Ii-air cores zihlala zisetyenziswa kwizicelo ze-radio-frequency, ezifana ne-induction heating, i-radio transmission, kunye ne-high-frequency transformers.

Ii-air cores zinenzuzo yokulahleka okuphantsi kunye nomgca ophezulu, okuvumela ukuhanjiswa kwesignali ngokuchanekileyo nangokuchanekileyo. Nangona kunjalo, zine-inductance ephantsi xa kuthelekiswa nezinye iintlobo ze-core, nto leyo ethintela ukusetyenziswa kwazo kwizicelo ezifuna amandla aphezulu emagnethi.

Isishwankathelo

Ukuqukumbela, ii-transformer cores zizinto ezibalulekileyo ezidlala indima ebalulekileyo ekudlulisweni nasekusasazweni kwamandla ombane. Ukuqonda iintlobo ezahlukeneyo zee-transformer cores, ukusuka kwii-iron zemveli kunye nee-silicon steel cores ukuya kwii-modern alloy amorphous kunye nee-ferrite cores, kunceda ekukhetheni izinto eziphambili ezifanelekileyo kwizicelo ezithile. Ukukhethwa kwezinto eziphambili kuxhomekeke kwizinto ezifana ne-frequency yokusebenza, amanqanaba ombane, iimfuno zokusebenza kakuhle, kunye nokuqwalaselwa kweendleko. Ngokukhetha ngononophelo i-transformer core efanelekileyo, iinjineli zinokuphucula ukusebenza kwe-transformer, zinciphise ilahleko yamandla, kwaye ziqinisekise ukunikezelwa kwamandla okuthembekileyo nokusebenzayo.
